Abstract

A disk-shaped record carrier which has circular or spiral recording tracks in the radial direction maintaining a predetermined pitch, each recording track being provided with a pre-group (2) which consists of protruding strips or a recessed strips, and with discrete signal discrimination portions (7, 9) of a protruding or recessed shape. The signal discrimination portions (7, 9) are so arranged that they will not be adjacent to each other between the neighboring recording tracks. This makes it possible to reduce crosstalk between the signal discrimination portions (7, 9) of the neighboring recording tracks at the time of reproducing data, so as to stably and correctly reproduce the discrimination signals.
